Our LS1 and GenIII truck engine harnesses are made from high- quality TXL rated wire. Each harness is covered in high temp mesh covering for flexibility. Every terminal is crimped and soldered to avoid corrosion and contact problems.
The harness includes a fuse box, OBDII diagnostic port with SES light, GM fuel pump relay and easy 4-wire hook up.

This makes it an easy plug-n-play design.
